Mommy! Hello everyone! We've been three months, and there are constant tantrums every day. Can't just lie down, constantly on my arms, and sometimes even on my arms. Doctors diagnosed it as hypoxia, we're treating it. But colic should end too. We go to bed at night and sleep until morning. Even if something bothered us, it would come in the middle of the night. Has anyone experienced this? What could be the cause?
